Metastatic castration resistant prostate cancer (CRPC) is an inevitably fatal disease. However, in recent years, several treatments have been shown to improve the outcome of CRPC patients both in the non-metastatic (nmCRPC) as well as the metastatic setting (mCRPC). In nmCRPC patients with a PSA doubling time < 10 months, the addition of enzalutamide, apalutamide and darolutamide to androgen deprivation therapy (ADT) compared to ADT alone resulted in improved metastases free (MFS) and overall survival (OS). For mCRPC patients, several treatment options have been shown to be effective: two taxane based chemotherapies (docetaxel and cabazitaxel), two androgen-receptor pathway inhibitors (ARPI) (abiraterone and enzalutamide), two radiopharmaceutical agents (radium 223 and 177Lutetium-PSMA-617), one immunotherapy treatment (sipuleucel-T) and two poly ADP-ribose polymerase (PARP) inhibitors (olaparib and rucaparib). Pembrolizumab is US Food and Drug Administration (FDA) approved in all MSI high solid tumors, although a very small proportion of prostate cancer patients harboring this characteristic will benefit. Despite having a broad variety of treatments available, there are still several unmet clinical needs for CRPC. The objective of this review was to describe the therapeutic landscape in CRPC patients, to identify criteria for selecting patients for specific treatments currently available, and to address the current challenges in this setting.

The purpose of our study is to investigate the prognostic value of phosphatase and tensin homolog on chromosome 10 (PTEN) expression in patients with de novo metastatic castration naïve prostate cancer (mCNPC). A total of 205 patients with mCNPC at Fudan University Shanghai Cancer Center (Shanghai, China) were retrospectively examined. Immunohistochemical staining of PTEN was performed on prostate biopsy samples of these patients. Associations among clinicopathological features, patient survival and PTEN protein expression were analyzed. PTEN loss occurred in 58 of 205 (28.3%) patients. Loss of PTEN was significantly correlated with high metastatic volume (P = 0.017). No association between PTEN expression and Gleason score was observed. Patients with PTEN loss had significantly shorter progression-free survival (PFS, P < 0.001) and overall survival (OS, P < 0.001) compared with patients with intact PTEN expression. Multivariate analysis showed that elevated alkaline phosphatase, high metastatic volume and PTEN loss were independent poor prognostic factors for PFS. The Eastern Cooperative Oncology Group performance status (ECOG PS) ≥2 and PTEN loss were independent poor prognostic factors for OS. The adjusted hazard ratio of PTEN loss for PFS and OS was 1.67 (95% confidence interval [CI]: 1.14-2.43, P = 0.008) and 1.95 (95% CI: 1.23-3.10, P = 0.005), respectively. PTEN loss was also significantly associated with shorter PFS (P = 0.025) and OS (P < 0.001) in patients with low-volume metastatic disease. Our data showed that PTEN loss is an independent predictor for shorter PFS and OS in patients with de novo mCNPC.

Several studies have suggested that prostate-specific antigen (PSA) in young men may predict the risk of developing prostate cancer (PC). Our aim is to study baseline PSA as a prognostic factor in the lifetime risk of developing PC, clinically significant PC (csPC), and metastatic PC (mPC), as well as to assess its impact on long-term mortality. This study was a retrospective analysis involving 2,415 men aged 45-70 years, all participants in the Spanish arm of the European Randomized Study of Screening for Prostate Cancer (ERSPC). These men underwent PSA testing, and prostate biopsies were performed if their PSA levels were ≥3 ng/ml. The follow-up period spanned from September 2, 1996, to February 11, 2021. Kaplan-Meier survival analysis was conducted to calculate the probability of prostate cancer diagnosis and death. The relationship between these probabilities and baseline PSA levels was assessed using the log-rank test. After 25 years of follow-up, the probability of being free of a diagnosis of PC was 95.5%, 89.6%, 80.0%, and 69.4%; and of PC death: 99.6%, 99.6%, 98.9%, and 98.3% for the categories of PSA <1 ng/ml, 1-1.9 ng/ml, 2-2.9 ng/ml, and >3 ng/ml, respectively. There is an association between baseline PSA level and the probability of PC diagnosis (which is maintained in age stratification), csPC, mPC (p <0.001), and PC death (p = 0.047). There is a clear relationship between baseline PSA and the probability of detection of PC, csPC and mPC during follow-up, as well as PC death, in a cohort belonging to the Spanish branch of the ERSPC, with a median follow-up of more than 23 years. Baseline PSA level can be used to define the most appropriate PC screening interval for everyone.

Objective To evaluate the efficacy and safety of apalutamide prostate cancer compared to the pivotal trials patients and to identify the first subsequent therapy in a real‐world setting. Methods The study is prospective and observational based on real‐world evidence, performed by different medical disciplines and eight academics centres around Barcelona, Spain. It included all patients with metastatic hormone‐sensitive prostate cancer (mHSPC) and high‐risk non‐metastatic castration‐resistant prostate cancer (nmCRPC) treated with apalutamide from June 2018 to December 2022. Results Of 227 patients treated with apalutamide, 10% had ECOG‐PS 2, and 41% were diagnosed with new‐generation imaging. In the mHSPC group (209 patients), 75 years was the median age, 53% had synchronous metastases, and 22% were M1a. In the nmCRPC (18 patients), 82 years was the median age, and 81% ≤6 months had PSA doubling time. Patients achieved PSA90 in 92% of mHSPC and 50% of nmCRPC and PSA ≤0.2 in 71% of mHSPC and 39% of nmCRPC. Treatment‐related adverse events occurred in 40.1% of mHSPC and 44.4% of nmCRPC. After discontinuation of apalutamide due to disease progression, 54.5% in mHSPC and 75% in nmCRPC started chemotherapy, while after discontinuation because of adverse events, 73.3% in mHSPC and 100% in nmCRPC continued with other hormonal‐therapies. Conclusions The efficacy and safety of apalutamide were similar to that described in the pivotal trials, despite including an older and more comorbid population. Usually, subsequent therapies after apalutamide differed depending on the reason for discontinuation: by disease progression started chemotherapy and by adverse events hormonal sequencing.

To report the regional locations of metastases and to estimate the prognostic value of the pattern of regional metastases in men with metastatic hormone-sensitive prostate cancer (mHSPC), we retrospectively analyzed 870 mHSPC patients between November 28, 2009, and February 4, 2021, from West China Hospital in Chengdu, China. The patients were initially classified into 5 subgroups according to metastatic patterns as follows: simple bone metastases (G1), concomitant bone and regional lymph node (LN) metastases (G2), concomitant bone and nonregional LN (NRLN) metastases (G3), lung metastases (G4), and liver metastases (G5). In addition, patients in the G3 group were subclassified as G3a and G3b based on the LN metastatic plane (below or above the diaphragm, respectively). The associations of different metastatic patterns with castration-resistant prostate cancer-free survival (CFS) and overall survival (OS) were analyzed by univariate and multivariate analyses. The results showed that patients in G1 and G2 had relatively favorable clinical outcomes, patients in G3a and G4 had intermediate prognoses, and patients in G3b and G5 had the worst survival outcomes. We observed that patients in G3b had outcomes comparable to those in G5 but had a significantly worse prognosis than patients in G3a (median CFS: 8.2 months vs 14.3 months, P = 0.015; median OS: 38.1 months vs 45.8 months, P = 0.038). In conclusion, metastatic site can predict the prognosis of patients with mHSPC, and the presence of concomitant bone and NRLN metastases is a valuable prognostic factor. Furthermore, our findings indicate that the farther the NRLNs are located, the more aggressive the disease is.

Our aim is to evaluate the association between body mass index (BMI) and preoperative total testosterone (TT) levels with the risk of single and multiple metastatic lymph node invasion (LNI) in prostate cancer patients undergoing radical prostatectomy and extended pelvic lymph node dissection. Preoperative BMI, basal levels of TT, and prostate-specific antigen (PSA) were evaluated in 361 consecutive patients undergoing radical prostatectomy with extended pelvic lymph node dissection between 2014 and 2017. Patients were grouped into either nonmetastatic, one, or more than one metastatic lymph node invasion groups. The association among clinical factors and LNI was evaluated. LNI was detected in 52 (14.4%) patients: 28 (7.8%) cases had one metastatic node and 24 (6.6%) had more than one metastatic node. In the overall study population, BMI correlated inversely with TT (r = −0.256; P < 0.0001). In patients without metastases, BMI inversely correlated with TT (r = −0.282; P < 0.0001). In patients with metastasis, this correlation was lost. In the overall study population, BMI (odds ratio [OR] = 1.268; P = 0.005) was the only independent clinical factor associated with the risk of multiple metastatic LNI compared to cases with one metastatic node. In the nonmetastatic group, TT was lower in patients with BMI >28 kg m−2 (P < 0.0001). In patients with any LNI, this association was lost (P = 0.232). The median number of positive nodes was higher in patients with BMI >28 kg m−2 (P = 0.048). In our study, overweight and obese patients had a higher risk of harboring multiple prostate cancer lymph node metastases and lower TT levels when compared to patients with normal BMI.

Integrating liquid biopsies of circulating tumor cells (CTCs) and cell-free DNA (cfDNA) with other minimally invasive measures may yield more comprehensive disease profiles. We evaluated the feasibility of concurrent cellular and molecular analysis of CTCs and cfDNA combined with radiomic analysis of CT scans from patients with metastatic castration-resistant PC (mCRPC). CTCs from 22 patients were enumerated, stained for PC-relevant markers, and clustered based on morphometric and immunofluorescent features using machine learning. DNA from single CTCs, matched cfDNA, and buffy coats was sequenced using a targeted amplicon cancer hotspot panel. Radiomic analysis was performed on bone metastases identified on CT scans from the same patients. CTCs were detected in 77% of patients and clustered reproducibly. cfDNA sequencing had high sensitivity (98.8%) for germline variants compared to WBC. Shared and unique somatic variants in PC-related genes were detected in cfDNA in 45% of patients (MAF > 0.1%) and in CTCs in 92% of patients (MAF > 10%). Radiomic analysis identified a signature that strongly correlated with CTC count and plasma cfDNA level. Integration of cellular, molecular, and radiomic data in a multi-parametric approach is feasible, yielding complementary profiles that may enable more comprehensive non-invasive disease modeling and prediction.

Introduction and Aims: Androgen deprivation therapy (ADT) with systemic anti-cancer treatment (SACT) ± palliative radiotherapy (pRT) is the current standard of care for Oligo-metastatic hormone-sensitive prostate cancer (o-mHSPC). Cytoreductive radical prostatectomy (cRP) has gained interest in this group of patients, with potential benefits including reduced tumour burden and a lower risk of local events from disease progression. In this review, we compare both survival outcomes and local event rates between cRP and upfront ADT ± SACT. Methods: All randomised trials and observational studies comparing cRP with standard treatment (ST), which we defined as ADT ± SACT for o-mHSPC, were included in the review. The study protocol was registered in PROSPERO (CRD42024516586), and the review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The databases searched included Embase, Medline, Cochrane Library, PubMed, and Web of Science. A risk of bias assessment was performed for the included studies as recommended by the Cochrane Handbook of Systematic Reviews and Interventions. The primary outcome measures were Overall Survival (OS), Cancer-Specific Survival (CSS), Progression-free Survival (PFS), Castrate-resistant Prostate Cancer-free Survival (CRPC-FS), and local complication rates. The secondary outcome measures were complication rates and functional outcomes post-cRP. Results: A total of 5130 studies were identified for this review (5119 by database searching and 11 through manual searching). Eight studies were included in the review, comprising 611 patients. cRP was identified to have superior OS (HR: 0.56 (95% CI: 0.34–0.92), I2 = 0%, p = 0.02 (very low certainty)) and CSS (HR: 0.27 (95% CI: 0.15–0.47), I2 = 0%, p < 0.0001 (very low certainty)). The PFS (HR: 0.67 (95% CI: 0.34–1.33), I2 = 58%, p = 0.25 (very low certainty)) and CRPC-FS (HR: 0.67 (95% CI: 0.32–1.43), I2 = 57%, p = 0.30 (very low certainty)) were similar between the two groups. The rates of local events were significantly lower in patients undergoing cRP (RR 0.27 (95% CI: 0.13–0.59), I2 = 17%, p = 0.001 (low certainty)). The rates of Clavien–Dindo (CD) grade 3 or higher complications ranged from 0% to 13.1%. Additionally, the reported continence rates ranged from 81.5% to 91.3%. The review is limited by the lack of a uniform definition for o-mHSPC and the predominance of low-quality, heterogeneous studies. Despite mitigation strategies, the overall certainty of evidence remains very low per GRADE assessment. Conclusion: cRP significantly reduces local event rates compared with ST and offers comparable PFS and CFPC-FS, with superior OS and CSS in the cRP arm compared to the ST arm in patients with o-mHSPC. However, there is a paucity of high-quality literature on this subject. Ongoing randomised controlled trials may soon clarify the role of cRP in the context of o-mHSPC concerning survival benefits.

The treatment landscape of advanced prostate cancer has completely changed during the last decades. Chemotherapy (docetaxel, cabazitaxel), androgen-receptor signaling inhibitors (ARSi) (abiraterone acetate, enzalutamide), and radium-223 have revolutionized the management of metastatic castration-resistant prostate cancer (mCRPC). Lutetium-177–PSMA-617 is also going to become another treatment option for these patients. In addition, docetaxel, abiraterone acetate, apalutamide, enzalutamide, and radiotherapy to primary tumor have demonstrated the ability to significantly prolong the survival of patients with metastatic hormone-sensitive prostate cancer (mHSPC). Finally, apalutamide, enzalutamide, and darolutamide have recently provided impactful data in patients with nonmetastatic castration-resistant disease (nmCRPC). However, which is the best treatment sequence for patients with advanced prostate cancer? This comprehensive review aims at discussing the available literature data to identify the optimal sequencing approaches in patients with prostate cancer at different disease stages. Our work also highlights the potential impact of predictive biomarkers in treatment sequencing and exploring the role of specific agents (i.e., olaparib, rucaparib, talazoparib, niraparib, and ipatasertib) in biomarker-selected populations of patients with prostate cancer (i.e., those harboring alterations in DNA damage and response genes or PTEN).

The pretreatment serum albumin/globulin ratio (AGR) has been used as a prognostic biomarker for various cancer types. However, the prognostic value of the AGR for prostate cancer, especially for metastatic prostate cancer (mPCa) after maximal androgen blockade (MAB), remains unclear. The aim of this study was to evaluate the prognostic value of the pretreatment serum AGR for mPCa treated with MAB. This retrospective study included 214 mPCa patients receiving MAB from October 2007 to March 2017. The correlation of the AGR with survival was estimated using Kaplan-Meier analysis and Cox proportional hazards models. The cutoff value of the AGR was 1.45 according to the receiver operating characteristic curve. Kaplan-Meier analysis demonstrated that patients with a low AGR (<1.45) had poor outcomes in terms of progression-free survival (PFS) and cancer-specific survival (CSS). Multivariate Cox analyses showed that the AGR was an independent predictor of PFS (hazard ratio [HR] = 0.642; 95% confidence interval [CI]: 0.430-0.957; P = 0.030) and CSS (HR = 0.412; 95% CI: 0.259-0.654; P < 0.001). Furthermore, in a subset of 79 patients with normal serum albumin levels (≥40.0 g l−1), the serum AGR remained an independent predictor of CSS (P = 0.009). The pretreatment AGR was an independent prognostic biomarker for PFS and CSS in patients with mPCa receiving MAB. In addition, the AGR remained effective for the prediction of CSS in patients with normal albumin levels (≥40 g l−1). However, further prospective studies are needed to confirm our conclusions.
